Fix datatable on notebook reloading
URL: https://github.com/apache/beam/pull/11262
1. The problem: when a user reloads the browser window of a jupyter
notebook page, the javascripts of all output areas are executed
in an arbitrary order. A datatable's state is gone on the reloading,
thus causing all the javascripts to reinitialize a datatable.
When the Javascripts race with each other, a datatable can be
reinitialized multiple times indeterminably, resulting in multiple
duplicated datatable wrappers being added to the DOM. The datatable
is then rendered with multiple search and pagination web elements.
2. The solution is to disable the javascripts from being executed on
reloading. There is no use of restoring a datatable's state because
the whole window is gone on reloading, thus nothing depends on the
datatable any more. And from the perspective of visualization, the
DOM with datatable web elements already presents, so no need for
datatable javascripts either.
3. Changed the dataframe visualization javascripts to check if a
datatable wrapper exists before invoking an initialization. If there
is no datatable object but there is a wrapper, it means this is a
browser reloading and do nothing.
